I'm not sure if those numbers are bad enough to count as "absolute garbage", but they're bad.

Overall, the general medical/physiological picture of pro athletes is not one of privilege, though there are corners to that picture that imply privilege.

The big picture physiologically is 1 step forward and 2 steps back, you're pointing out that the 1 step forward is a privilege. You're correct: the 1-step forward is a privilege.

Meanwhile the life expectancy of an Olympic athlete is higher than the average.
Again, you compared the health of an athlete to the one of a drug addicted anorexic. Talk about an over exaggeration.
Lets get back to what was actually being discussed, the fitness level.
Regardless of whether or not a player suffers long term damaging injuries or not, having some of the best coaches in the world is a privilege. Whether it is worth the injury risk or not is another question.
They worked hard to get where they are, and they deserve that privilege.
Also, I don't consider a 73yo life expectancy to be that bad at all.
